Falcon
Free, open-source SQL client for Windows and Mac
Falcon is a free, open-source SQL editor with inline data visualization.

FileSaver.js
An HTML5 saveAs() FileSaver implementation
Have you ever wanted to add a Save as… button to a webapp? Whether you’re making an advanced WebGL-powered CAD webapp and want to save 3D object files or you just want to save plain text files in a simple Markdown text editor, saving files in the browser has always been a tricky business. Usually when you want to save a file generated with JavaScript, you have to send the data to your server and then return the data right back with a Content-disposition: attachment header. This is less than ideal for webapps that need to work offline. The W3C File API includes a FileSaver interface, which makes saving generated data as easy as saveAs(data, filename), though unfortunately it will eventually be removed from the spec. With FileSaver.js, which implements FileSaver in all modern browsers, it’s possible to generate any type of file you want right in the browser, document editors can have an instant save button that doesn’t rely on an online connection. -

GSD Core
Meta-prompting, context engineering, spec-driven development system
GSD Core is the core framework behind Open GSD, a workflow system for AI-assisted software engineering. It is designed to keep agent-driven development organized by turning vague goals into structured research, plans, tasks, implementation phases, verification steps, and handoffs. The project focuses on cleaner context, verified work, and more honest project history when working with coding agents. It supports installation across several AI coding runtimes and offers profiles for different levels of workflow surface area. The system is especially useful for developers who use AI agents heavily and need more discipline around planning, execution, and review. It acts less like a single app and more like an execution layer for shipping software with agents. -

Jesse
An advanced crypto trading bot written in Python
Jesse is an open-source AI agent framework designed to help developers build and orchestrate intelligent workflows that combine large language models (LLMs) with external tools, automation logic, and real-world actions. It acts as an agent manager where you can define tasks, contexts, and tool integrations so that AI reasoning is reliably connected to deterministic procedures like API calls, data retrieval, and task execution. Jesse emphasizes structured outputs, safety boundaries, and explainable reasoning, helping users design agents that don’t just hallucinate responses but can coordinate steps, validate conditions, and interact with systems predictably. It also includes built-in support for evaluation, logging, and orchestration so developers can monitor, test, and improve agent behavior over time. Because it’s framework-agnostic with respect to model providers, Jesse can work with different LLM backends, giving teams flexibility in cost and capability trade-offs. -

Koa
Expressive middleware for node.js using ES2017 async functions
Koa is a minimal, expressive web framework for Node.js created by the team behind Express, built around modern JavaScript features. Its middleware system uses async functions and an “onion” execution model, producing clean, sequential control flow for request/response handling. Koa keeps the core small and unopinionated—there’s no built-in router or templating—so developers compose only the pieces they need. The framework exposes a refined Context object to standardize request and response utilities without obscuring Node’s primitives. This design encourages readable middleware, robust error handling, and straightforward composition for tasks like authentication, logging, and body parsing. In production, Koa’s simplicity and async-first approach translate to predictable performance and maintainable server code. -

The README explains how users can create their own M3U subscription link by editing a sample playlist and hosting it through GitHub Pages. It also exposes an EPG interface and web tools for tasks such as M3U8 downloading and format conversion. The project states that it does not store streaming media itself, so it is best viewed as an icon, playlist, and utility resource for testing and personal configuration. -
